Notify ops staff when contact stop status changes

Operations coordinators miss cancellations when contacts flip to 'stop', causing duplicate alerts and missed processing. Send a single alert per contact when stop flips so staff follow up immediately.

Overview

Operations coordinators risk duplicated work and missed cancellations when stop signals are ignored. This workflow delivers one reliable alert per contact and preserves a simple announced flag, so staff follow up promptly and duplicate notifications disappear.
